Geochronology,Geochemistry and Sr-Nd-Hf Isotopes of Early-Middle Triassic Adakitic Plutons in Central-eastern Jilin Province,NE China:Constraints on the Non-synchronous Closure of Paleo-Asian Ocean
文献摘要：
The Changchun-Yanji suture zone(CYSZ)in NE China is considered as the suture between the North China Craton(NCC)and Central Asian Orogenic Belt(CAOB).The geochronology,geochemistry and Sr-Nd-Hf isotopes of Early-Middle Triassic adakitic plutions from the CYSZ,are presented in this paper to discuss their petrogenesis and tectonic setting,as well as to constrain the timing and style of the Paleo-Asian Ocean's final closure.In Early Triassic,the Dayushan pluton(ca.250 Ma)from western CYSZ has negative εNd(t)values,bidirectional provenances(NCC and CAOB)of εHf(t),which are formed in a collision tectonic setting.In contrast,in eastern CYSZ,the early Triassic samples in Liangshan(ca.242 Ma)were high Mg#values,positiveεNd(t),single provenances(CAOB)of εHf(t)resulting from a subduction setting.In the Middle Triassic,the A-type granites in western CYSZ are found in previous studies representing a post-collisional extensional environment,whereas syn-collisional Lianyanfeng granites(ca.237 Ma)in eastern CYSZ with low ISr and large scale εNd(t)and εHf(t)values from bidirectional provenances(NCC and CAOB),represent a collisional setting.The Paleo-Asian Ocean's occurred in a scissor-like fashion along the CYSZ during the Triassic period.
